DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. First, as exemplified in FIG. 1, an optical data transfer device 1 of the present invention is assumed to be used for a bar code system, and includes a portable handy terminal 2 and a printer main body 3 as a data processing device. ing.

The printer body 3 is provided with a shoulder belt 4 having an adjustable length above both sides and a belt handle 6 on one side.
Here, the housing of the printer body 3 has a structure in which a printer cover 9 and an interface cover 10 are connected in parallel on a front cover 7 and a rear cover 8 which are connected from the front and rear. Here, a horizontally long mount discharge port 11 is formed between the front cover 7 and the lower edge of the printer cover 9, and a horizontally long label issuing port 12 is formed on the front surface of the printer cover 9. In the optical data transfer device 1, an information input hole 13 is formed on the front surface of the interface cover 10, and an annular convex portion is formed by a support ring 14 attached to the outer peripheral portion.

On the other hand, the handy terminal 2 is also a bar code scanner is protruded information output projection 16 on the distal end surface of one end which is formed in collision portion 15a of the housing 15, a keyboard on the upper surface of the housing 15 1
7 and a display 18 are arranged. The information output projection 16 of the handy terminal 2 is formed in a tapered shape with a step like connecting a cone to a cylinder.
Optical lens 19 is mounted on its tip.

Here, as exemplified in FIG. 2, an inner frame 20 having a conical concave wall portion for forming the information input hole 13 is provided on the back side of the interface cover 10 of the printer body 3. And a PCB (Printed Circuit Board) 22 having a light receiving element 21 mounted on the front surface are sequentially located by screwing or the like. An elastic member 23 which is also a light shielding member is mounted between the inner peripheral surface of the concave wall portion of the inner frame 20 and the back surface of the interface cover 10. Here, as illustrated in FIG. 4, the elastic member 23 forms a dome-shaped portion 23 b having a cross-shaped slit 23 a into a large or small O-shaped portion.
It is shaped like a ring attached to an annular portion 23c, and when the dome-shaped portion 23b is pressed from inside, the slit 23a, which is normally shielded by elasticity, is opened. ing. A protective filter 25 is attached to a light transmitting hole 24 formed at the innermost portion of the concave wall portion of the inner frame 20.
The light receiving elements 21 of the CB 22 face each other.

In the optical data transfer apparatus 1 having such a configuration, when commodity data is input to the handy terminal 2 by operating the keyboard 17 or scanning a bar code with the optical lens 19, the data is transferred to the RAM.
(Random Access Memory) or the like. Therefore, the information output projection 16 of the handy terminal 2 storing the product data is connected to the printer main body 3.
The product data is output as an optical signal from the optical lens 19 at the tip of the information output projection 16 of the handy terminal 2 and received by the light receiving element 21 of the printer body 3 when the keyboard 17 is operated by inserting the information input hole 13 into the information input hole 13. You. Therefore, according to the product data photoelectrically converted by the light receiving element 21, operations such as issuance of a barcode label and management of product information are performed.

As described above, in the optical data transfer device 1, the product data is transferred by attaching and detaching the handy terminal 2 to and from the printer main body 3. Therefore, it is necessary to connect the data transfer means with a cable. However, since they can be operated separately, it is possible to contribute to improvement of work efficiency. Further, since data transfer from the handy terminal 2 to the printer main body 3 is performed by optical communication, for example, a bar code reading illumination or the like can be used as the data output light emitting unit 29. In this case, the optical system of the existing handy terminal (not shown) can be used, so that the structure is simple and the number of parts is prevented from increasing, so that the implementation is easy.

In this optical data transfer apparatus 1, when the information output projection 16 of the handy terminal 2 is inserted into the information input hole 13 of the printer body 3 as described above, as shown in FIG. The slit 23a of the dome-shaped portion 23b of the elastic member 23 pressed by the output protrusion 16
Is opened, and at the same time, the information output projection 16 is
While being elastically held by third annular portion 23c, the a collision portion 15a of the handy terminal 2 printer body 3
Abuts on the support ring 14. Then, by this contact, the handy terminal 2 is accurately held by the printer main body 3, and the slit 23 of the elastic member 23 is opened.
a and the light transmitting hole 24 of the inner frame 20 and the protective filter 2
5, the optical lens 19 of the information output protrusion 16
The CB 22 is accurately positioned and held with respect to the light receiving element 21. That is, in the optical data transfer device 1, the handy terminal 2 connected to the printer main body 3 has the information output projection 16 elastically held by the elastic member 23 in the information input hole 13 and the support ring of the printer main body 3. a collision portion 15a of 14 the housing 15 is better retained by abutment. Therefore, in the optical data transfer apparatus 1, the optical path for data transfer is formed very accurately, the SN ratio is high, and it becomes unnecessary to hold the handy terminal 2 during the transfer of the product data by hand. Operability is also good.

The optical data transfer apparatus 1 according to the present embodiment.
In FIG. 2, as illustrated in FIG. 2, two arc-shaped engagement holes 26 having a large width are formed partially around the information input hole 13 of the interface cover 10. A holding hole 27 is formed on the front surface of the inner frame 20 at a position facing the narrow portion. Then, the two engaging claws 28 projecting from the back surface of the support ring 14 are inserted into the wide portions of the engaging holes 26 of the interface cover 10 and rotated to the narrow portions, and in this state, the interface cover is rotated. By fixing the inner frame 20 to the engaging frame 10, the tip of the engaging claw 28 penetrating the engaging hole 26 of the interface cover 10 is
Is to be held in position. By doing so, in the optical data transfer device 1, the support ring 14 can be easily attached to the interface cover 10 without using any tools, so that the productivity is extremely good. Further, in such an optical data transfer device 1, since a support ring of another shape (not shown) can be attached to the interface cover 10, it is easy to cope with a case where the design is changed.

In the optical data transfer device 1,
The light receiving element 21 mounted in the information input hole 13 of the printer main body 3 is shielded from light by the dome-shaped portion 23b of the elastic member 23, thereby preventing malfunction due to optical noise entering through the opening of the information input hole 13. Have been. Moreover, the elastic member 2 that shields the light receiving element 21 of the printer body 3 from light.
3, the dome-shaped portion 23b is opened and closed around the slit 23a in response to pressing from the inside, so that the information output projection 16 of the handy terminal 2 is automatically inserted and removed from the information input hole 13 of the printer main body 3. It operates automatically and does not require dedicated control or operation. Further, in the optical data transfer device 1 of the present embodiment, the dome-shaped portion 23b that shields the light receiving element 21 of the printer main body 3 and the annular portion 23c that holds the information output projection 16 of the handy terminal 2 are formed by the elastic member 23. As a result, the number of components and the number of manufacturing steps are reduced, and productivity is improved.

The optical data transfer device 1 according to the present embodiment
In the above, the information output projection 16 of the handy terminal 2 is held by the annular portion 23c of the elastic member 23 of the printer main body 3. However, as illustrated in FIG. 23 slits 23
a is held at the leading edge.
