Description

This disclosure relates to a printing apparatus.

In printing machines that print on printing tape, the printing tape is replaced and supplied by attaching and detaching a cassette containing the printing tape to the main body of the printing machine. In such cassettes, a configuration in which the cassette is inserted into an opening provided in the housing of the main body of the printing machine is known (see Patent Document 1).

Patent No. 5309222

In the aforementioned enclosure, the printed tape is ejected with the printed side tilted downwards relative to the main surface where the input section is located. Therefore, it is difficult for the user to check the printing results on the tape.

One aspect of this disclosure aims to provide a printing apparatus that makes it easy to check the printing results of printed tapes.

One aspect of this disclosure is a printing apparatus comprising a housing having a cassette housing section into which a printing cassette containing a roll of printing tape can be mounted, a print head provided within the cassette housing section for printing on the printing tape, and an input section provided in the housing.

The print head has multiple heating elements arranged side-by-side along a scanning direction that intersects a virtual plane perpendicular to the insertion direction of the print cassette into the cassette housing. The insertion opening of the cassette housing is located above the input unit when the input unit is in use.

The enclosure has a main surface on which the input section is located, a side surface that intersects both the main surface and the virtual surface, and an outlet on the side surface for ejecting the printed tape. The angle between the normal direction of the printed surface of the tape at the outlet and the normal direction of the main surface is less than 45°.

With this configuration, the user can simultaneously view the printed side of the printed tape at the output port and the main side where the input section is located. Therefore, it is easier for the user to check the printing results of the printed tape.

[1. First Embodiment]
[1-1. Structure]
The printing apparatus 1 shown in Figures 1 and 2 comprises a printing apparatus body 10 and a printing cassette 100. The printing apparatus 1 is a device that prints on a tape-shaped printing medium.

In this embodiment, the axis parallel to the left-right direction (i.e., the width direction) of the main surface 21 is defined as the X-axis, the axis parallel to the up-down direction of the main surface 21 (i.e., the axis parallel to the main surface 21 and perpendicular to the X-axis) is defined as the Y-axis, and the axis parallel to the normal direction of the main surface 21 is defined as the Z-axis.

<Printing device body>
The printing device body 10 comprises a housing 11, an input unit 12, and a display unit 13. Furthermore, as shown in Figures 3A and 3B, the printing device body 10 also comprises a print head 14, a platen roller 15, a roller holder 16, a drive shaft 17, and a lever 18.

(Cabinet)
As shown in Figure 2, the housing 11 has a cassette storage section 11A, an outlet 11B, and a finger rest 11C.

(Cassette storage compartment)
The cassette housing section 11A is a space into which a printing cassette 100 can be installed. The cassette housing section 11A has an insertion opening provided on the upper surface 22 of the housing 11. The printing cassette 100 is inserted into the cassette housing section 11A along a direction perpendicular to the upper surface 22 (i.e., the normal direction of the upper surface 22).

The insertion direction of the printing cassette 100 into the cassette housing 11A intersects with the main surface 21 of the housing 11, where the input unit 12 and display unit 13 are located. The insertion opening of the cassette housing 11A is located above the input unit 12 and display unit 13 when the input unit 12 is in use. The upper surface 22, where the insertion opening of the cassette housing 11A is located, constitutes the upper end of the housing 11. The upper surface 22 intersects with both the Y-axis and the Z-axis.

The housing 11 exposes its outer surface 100A, which intersects with the central axis P of the first roll 101 (see Figure 6) in the printing cassette 100, through the insertion opening of the cassette housing 11A. The printing cassette 100 is inserted into the cassette housing 11A along a direction parallel to the central axis P.

The housing 11 does not have a lid to cover the printing cassette 100 installed in the cassette storage section 11A. The printing cassette 100 inserted into the cassette storage section 11A is engaged with the housing 11 by operating the lever 18 (see Figure 4A).

The cassette housing section 11A has an opening 11D that exposes a portion of the printing cassette 100 mounted in the cassette housing section 11A when viewed from the direction normal to the main surface 21. The opening 11D is provided continuously with the insertion opening of the cassette housing section 11A.

Specifically, the opening 11D is formed by recessing a portion of the edge of the cassette storage section 11A's insertion opening, specifically the edge closest to the main surface 21 (i.e., the upper edge in the vertical direction), downwards (i.e., toward the input section 12). In other words, the opening 11D is formed by a step created by offsetting a portion of the upper surface 22 downwards.

The opening 11D exposes a label 100B, which is attached to a surface intersecting the outer surface 100A of the printing cassette 100 (specifically, a surface parallel to the central axis P of the first roll 101), so that it can be seen when the input unit 12 is in use. This makes it easier for the user to identify the installed printing cassette 100.

(Exhaust port)
The discharge port 11B discharges the printed tape from inside the cassette housing 11A to the outside. The discharge port 11B is provided on the first side surface 23 of the housing 11. The discharge port 11B discharges the printed tape along the Y axis (i.e., in a direction perpendicular to the first side surface 23).

The first side surface 23 is a surface that intersects both the main surface 21 and a virtual surface (i.e., the top surface 22) perpendicular to the insertion direction of the printing cassette 100 into the cassette housing 11A. The first side surface 23 is located to the left of the main surface 21 when the input unit 12 is in use. Note that the second side surface 24 (see Figure 4A), which is opposite the first side surface 23, does not have an opening.

As shown in Figure 5, the angle φ between the normal direction T of the printed surface of the printing tape (i.e., the surface facing the printing head 14) and the normal direction N of the main surface 21 (i.e., the Z-axis) at the discharge port 11B is less than 45°.

In other words, with the housing 11 placed on a plane S such that the input unit 12 faces upward in the vertical direction, the printed tape is discharged from the discharge port 11B so that the printed side faces upward in the vertical direction and towards the input unit 12.

(Finger rest)
The finger rest portion 11C shown in Figures 4A and 4B is a recess provided continuously with the cassette storage portion 11A.

Specifically, the finger rest portion 11C is provided on the upper surface 22 at the edge facing the opening 11D in the cassette housing portion 11A. When the printing cassette 100 is installed in the cassette housing portion 11A, the printing cassette 100 is exposed within the finger rest portion 11C.

With the print cassette 100 installed in the cassette housing 11A, the user can remove the print cassette 100 from the cassette housing 11A by inserting their finger into the finger rest 11C.

(Input section)
The input unit 12 shown in Figure 1 is a keyboard that can input characters, symbols, etc. to be printed on the printing tape.

The input unit 12 consists of multiple keys or buttons arranged on the main surface 21 of the housing 11. The input unit 12 also includes operation keys for performing processing inputs such as print settings and print execution.

The main surface 21 is the surface where the functions for user input operations and display confirmation are concentrated when the printing device body 10 is in use. The user performs input operations while holding or placing the printing device body 10 in a position where the input unit 12 and display unit 13 are visible. The vertical length of the main surface 21 in the input unit 12's usage state is greater than its horizontal length.

(Display)
The display unit 13 displays the input content (i.e., the print content) from the input unit 12. The display unit 13 is composed of, for example, a liquid crystal display (LCD), an organic LED, or the like.

The display unit 13 is positioned on the main surface 21 of the housing 11. The display unit 13 is positioned closer to the insertion opening (i.e., the top surface 22) of the cassette storage unit 11A than to the input unit 12. In other words, the display unit 13 is positioned above the input unit 12 when it is in use, and below the insertion opening of the cassette storage unit 11A.

As shown in Figure 5, the cassette housing section 11A overlaps with a portion of the display section 13 in the direction normal to the main surface 21 (i.e., the direction parallel to the Z-axis).

(Print head)
The print head 14 shown in Figures 3A and 3B prints onto the print tape held by the print cassette 100.

The print head 14 is located within the cassette housing section 11A. The print head 14 has a plate shape, with its thickness direction parallel to the thickness direction of the printed tape discharged from the output port 11B.

The print head 14 has multiple heating elements (i.e., heating components) whose heating is individually controlled. The print tape, transported by the platen roller 15 to a position overlapping the print head 14, is pressed against the print head 14, which has been heated by the heating elements, via the ink ribbon. This transfers a portion of the ink on the surface of the ink ribbon to the print tape, printing characters, symbols, etc., onto the print tape.

Multiple heating elements constitute the printing surface 14A of the print head 14. Furthermore, the multiple heating elements are arranged side-by-side along a scanning direction that intersects a virtual surface (i.e., the upper surface 22) perpendicular to the insertion direction of the print cassette 100 into the cassette housing 11A. In this embodiment, the scanning direction is parallel to the insertion direction of the print cassette 100.

As shown in Figure 5, the printing surface 14A of the print head 14 is positioned to face downwards in the vertical direction, with the housing 11 mounted on a flat surface S such that the input unit 12 and the display unit 13 face upwards in the vertical direction.

Here, "the printing surface 14A faces downward in the vertical direction" means that the normal vector of the printing surface 14A includes a component pointing vertically downward. In other words, the print head 14 is pressed against the printing tape from above in the vertical direction.

Furthermore, when the housing 11 is placed on a plane S such that the input unit 12 and the display unit 13 face upward in the vertical direction, the normal vectors of the main surface 21 and the top surface 22 are both inclined with respect to the vertical direction and have a vertically upward component.

Furthermore, the first angle Θ1 formed by the main surface 21 and the virtual surface V (i.e., the top surface 22) perpendicular to the insertion direction of the printing cassette 100 into the cassette housing 11A on the outside of the housing 11 is 270° or greater. In other words, the second angle Θ2 formed by the main surface 21 and the virtual surface V on the inside of the housing 11 is less than 90°.

The first angle Θ1 is the angle between the principal surface 21 and the virtual surface V in a counterclockwise direction in the Y-Z plane, where the intersection line of the extended principal surface 21 and the virtual surface V is the origin O, and the normal vector of the principal surface 21 points to the first quadrant, and the principal surface 21 is the boundary between the first and fourth quadrants.

(Platen roller)
The platen roller 15 shown in Figures 3A and 3B is a roller for transporting the printing tape from inside the printing cassette 100 to the outside. The rotation axis of the platen roller 15 is parallel to the direction in which the printing cassette 100 is inserted into the cassette housing 11A (i.e., the scanning direction of the print head 14).

The platen roller 15 is positioned inside the housing 11, facing the print head 14. The platen roller 15 is held by a roller holder 16. The platen roller 15 is displaced by the movement of the roller holder 16 between a nip position (where it nips the print tape together with the print head 14, i.e., presses the print tape against the print head 14) and a non-nip position (where it is away from the print tape).

(Drive shaft)
The drive shaft 17 is located inside the housing 11. The drive shaft 17 is inserted into the printing cassette 100 within the cassette housing section 11A.

The drive shaft 17 inputs the driving force for winding the ink ribbon to the printing cassette 100. The rotation axis of the drive shaft 17 is parallel to the Y-axis. The drive shaft 17 rotates around its rotation axis by a drive source (not shown).

(lever)
The lever 18 shown in Figures 4A and 4B is a plate-shaped member that displaces the platen roller 15 between the nip position and the non-nip position. The lever 18 is connected to the roller holder 16 inside the housing 11.

The lever 18 is located on the back surface 25 of the housing 11. The back surface 25 is the surface opposite the main surface 21, with the print head 14 and platen roller 15 in between. The back surface 25 is inclined relative to the main surface 21. Furthermore, the back surface 25 is perpendicular to the top surface 22.

The lever 18 is displaceable between the locked position shown in Figure 4A and the unlocked position shown in Figure 4B. The lever 18 is pivotably connected to the housing 11 around a rotation axis parallel to the back surface 25.

In the locked position, the lever 18 is housed inside the housing 11 so that it is flush with the back surface 25. When the lever 18 moves to the locked position, the platen roller 15 moves to the nip position, and the printing cassette 100 is fixed to the housing 11.

In the release position, the lever 18 is raised relative to the back surface 25. When the lever 18 moves to the release position, the platen roller 15 moves to the non-nip position, and the printing cassette 100 is released from its fixed position.

<Printing Cassette>
The printing cassette 100 contains the printing tape, which is the printing medium. The printing cassette 100 is detachable from the printing device body 10. By replacing the printing cassette 100, the printing medium can be replenished and the type of printing medium (e.g., color, material, etc.) can be changed.

As shown in Figure 6, the printing cassette 100 comprises a first roll 101, a first supply spool 102, a second roll 103, a second supply spool 104, an input spool 105, a clutch spring holder 109, a first case 110A, a second case 110B, a third case 110C, and a fourth case 110D.

(case)
Case 110A, Case 210B, Case 310C, and Case 410D and Case 110 are divided cases that house the rolls, spools, and gears.

The case of the printing cassette 100 is a rectangular parallelepiped with sides parallel in the vertical direction, the front-to-back direction, and the left-to-right direction. The outer wall of the first case 110A facing the first roll 101 includes an outer surface 100A (see Figure 2) that intersects the central axis P.

The third case 110C is provided with a head opening 111 into which the print head 14 is inserted, while the print cassette 100 is mounted in the cassette housing section 11A. Printing onto the print tape is performed by the print head 14 in the head opening 111.

The width direction of the printed tape in the head opening 111 is parallel to the scanning direction in which the multiple heating elements of the print head 14 are aligned. The printed tape printed in the head opening 111 is discharged from the discharge port 11B of the housing 11.

(First roll)
The first roll 101 is a printing tape on which printing will be performed, wound around the first supply spool 102.

Printing is performed on the surface of the printing tape by the print head 14 and ink ribbon of the printing device body 10. Two spacer films 101A and 101B are positioned on the axial outer side of the first roll 101, sandwiching the first roll 101.

The central axis P of the first roll 101 is parallel to the insertion direction I of the printing cassette 100 into the cassette housing 11A. Furthermore, the first roll 101 is positioned offset from the head opening 111 in the insertion direction I.

Therefore, with the print cassette 100 installed in the cassette housing 11A, the multiple heating elements of the print head 14 are positioned differently from the first roll 101 in the scanning direction (i.e., the insertion direction I).

(First supply spool)
The first supply spool 102 is rotatable around its rotation axis. The first supply spool 102 rotates in conjunction with the transport of the printing tape by the platen roller 15 of the printing device body 10, thereby supplying the printing tape to the print head 14.

(Second roll)
The second roll 103 is an ink ribbon used for printing on the printing tape, wound around the second supply spool 104. The second roll 103 is positioned offset from the first roll 101 in the insertion direction I.

The ink ribbon is layered with the printing tape and used for printing by the print head 14. The ink ribbon used for printing is wound onto the input spool 105. The second roll 103 is subjected to rotational resistance by a clutch spring 109A held in the clutch spring holder 109.

(Second supply spool)
The second supply spool 104 is rotatable around its rotation axis. The second supply spool 104 rotates in conjunction with the winding of the ink ribbon by the input spool 105, thereby supplying the ink ribbon to the print head 14.

(Input spool)
The input spool 105 is rotatable around its rotation axis. Driving force is input to the input spool 105 from the drive shaft 17 of the printing device body 10.

<How to use the printing device>
The following describes the printing procedure on the printing tape in the printing device 1. First, the printing cassette 100 is inserted into the cassette housing section 11A of the printing device body 10.

After inserting the printing cassette 100, the lever 18 is moved from the unlocked position to the locked position. This moves the platen roller 15 to the nip position, and the printing device body 10 becomes ready for printing.

When the printer is ready to print, characters, symbols, etc., entered by the user via the input unit 12 are displayed on the display unit 13. After confirming the input on the display unit 13, the user enters a print command via the input unit 12. This causes the print head 14 to print onto the print tape in the print cassette 100.

The printed tape, printed by the print head 14, is discharged from the discharge port 11B. At this time, the printed tape is discharged from the housing 11 so that the printed side faces the user.

To replace the print cassette 100, the lever 18 is moved from the locked position to the unlocked position, thereby displacing the platen roller 15 to the non-nip position. Then, by inserting fingers into the finger rests 11C and opening 11D, the user can remove the print cassette 100 from the cassette housing 11A.

[1-2. Effects]
According to the embodiments described in detail above, the following effects can be obtained.
(1a) The user can simultaneously view the printed surface of the printed tape at the discharge port 11B and the main surface 21 on which the input section 12 is provided. Therefore, it is easy for the user to check the printing result of the printed tape.

(1b) In the mounting position where the input unit 12 faces upward, the printing surface 14A of the print head 14 faces downward, thereby suppressing dust accumulation on the print head 14 located within the cassette housing 11A. As a result, in a printing device body 10 having a housing 11 into which the print cassette 100 is inserted so that it is exposed, malfunctions of the print head 14 can be suppressed.

(1c) The cassette housing section 11A has an opening 11D that exposes a portion of the printing cassette 100 mounted in the cassette housing section 11A when viewed from the direction normal to the main surface 21, allowing the user to recognize the mounted printing cassette 100 when performing input operations.

(1d) By providing the lever 18 on the back surface 25 of the housing 11, space for the display unit 13 can be secured on the main surface 21 while allowing the printing surface 14A of the print head 14 to be directed in a predetermined direction.

(1e) The finger rest portion 11C makes it easy to remove the printing cassette 100 from the cassette storage portion 11A.
(1f) The cassette housing section 11A overlaps with the display section 13 in the direction normal to the main surface 21, thereby making the housing 11 smaller.

[2. Second Embodiment]
The printing apparatus 201 shown in Figure 7 comprises a printing apparatus body 210 and a printing cassette 100. The printing cassette 100 is the same as that of the printing apparatus 1 in Figure 1.

The printing device body 210 comprises a housing 211, an input unit 12, and a display unit 13. Furthermore, as shown in Figures 8A and 8B, the printing device body 210 also includes a print head 14, a platen roller 15, a roller holder 16, and a drive shaft 17. The configuration of the printing device body 210, excluding the housing 211, is the same as that of the printing device body 10 in Figure 1.

The housing 211 has a cassette storage section 211A, an outlet 211B, two finger rests 211C, and a lid 211E. The cassette storage section 211A is the same as the cassette storage section 11A in Figure 1, except that it does not have an opening 11D. The outlet 211B is the same as the outlet 11B in Figure 1.

The two finger rests 211C are recesses that are continuous with the cassette housing 211A. Specifically, the two finger rests 211C are located on the upper surface 22 of the housing 211, one on each of the two opposing edges of the cassette housing 211A in a direction parallel to the X-axis.

The lid 211E shown in Figure 9 is a component that covers the insertion opening of the cassette housing 211A. The lid 211E is detachably attached to the upper surface 22 of the housing 211. When attached to the housing 211, the lid 211E covers the printing cassette 100 mounted in the cassette housing 211A and the upper surface 22 of the housing 211 from the direction in which the printing cassette 100 is inserted into the cassette housing 211A.

The lid 211E has an opening 211F and a pressing portion 211G. The opening 211F exposes a portion of the printing cassette 100 mounted in the cassette housing portion 211A (specifically, the label 100B affixed across the outer surface 100A and the surface intersecting the outer surface 100A).

In detail, the opening 211F exposes a portion of the printing cassette 100 when viewed from the normal direction of the main surface 21 of the housing 211, and also exposes a portion of the printing cassette 100 when viewed from the normal direction of the upper surface 22 of the housing 211 (i.e., the insertion direction of the printing cassette 100). This allows the user to identify the printing cassette 100 from both the lid 211E side and the input section 12 side.

The pressing portion 211G is a rod-shaped part that protrudes from the inner surface of the lid 211E in the direction of mounting the lid 211E. The pressing portion 211G is inserted into the insertion hole 211H provided in the housing 211 when mounting the lid 211E to the housing 211. The insertion hole 211H extends from the upper surface 22 along the Y-axis.

The pressing part 211G, inserted into the insertion hole 211H, presses against the roller holder 16, moving the platen roller 15 to the nip position. In other words, the lid 211E has the function of protecting the printing cassette 100, as well as the function of moving the platen roller 15 to the nip position.

As shown in Figure 10, the printing apparatus body 210 may include a cutter lever 211I for operating a cutter (not shown) located inside the housing 211. Operating the cutter lever 211I moves the cutter, cutting the printed tape discharged from the discharge port 211B.
