沿つて移動するようになつている。 FIG. 1 is a perspective view showing a paper feed tray section to which a paper remaining amount display device according to an embodiment of the present invention is applied, with a side cover removed. In this device, a moving pin 3 is provided on the side surface of a paper feed tray 2 that moves up and down as the amount of paper decreases as the paper is fed by the paper feeder 1. This moving pin 3
protrudes from a vertical slot 4 provided on the side surface of the paper feed tray, and moves up and down as the paper feed tray moves up and down as paper is consumed. Two guide pins 5 are provided on the upper and lower sides of the paper feed tray, and these guide pins 5
An indicator member 6 is mounted so as to be movable in the horizontal direction with respect to the side surface thereof. A folded triangular indicator pointer 7 is provided at the upper end of the indicator member 6, and the upper side surface 7A of the indicator pointer 7 has the following features:
It is recommended to apply fluorescent paint such as green or red to make the display easier to read. The indicator member 6 is formed with an elongated slot 8 that extends linearly at an angle in the vertical direction, and the moving pin 3 directly engages with the elongated slot 8. Therefore, when the moving pin 3 moves up and down,
The indicator member 6 will move accordingly in the horizontal direction. A side cover 9 that covers the side surface of the paper feed tray 2 is formed with a remaining paper amount display window 10, and a remaining paper amount display scale 11 is provided in the horizontal direction on its downwardly inclined surface. FIG. 2 partially shows a front sectional view of the side cover 9 attached to the side surface of the paper feed tray 2. As shown in FIG. As clearly shown in this Figure 2,
The upper side surface 7A of the indicator pointer 7 of the indicator member 6 is configured to move relative to and along the remaining paper amount display scale 11.

で、実際の用紙残量を常に正確に読み取り易い。 According to the configuration of this paper remaining amount display device of the present invention, the amount of vertical movement of the paper feed tray 2 as the paper is consumed is linearly displayed as an indicator by the engagement between the moving pin 3 and the elongated slot 8. It is converted into the horizontal movement amount of the pointer 7, and the paper remaining amount display scale 11
By reading the relative position between the indicator pointer 7 and the indicator pointer 7, the remaining amount of paper can be known. Since the indicator pointer moves in the horizontal direction, the operator can always accurately and easily read the remaining amount without creating parallax with the display scale. Moreover, since the remaining amount is always displayed linearly, it is easy to always accurately read the actual remaining amount of paper.
また、本発明の用紙残量表示装置は、移動ピン
と細長スロツトとの係合によるだけのものである
から構造簡単で安価なものとされうる。 Further, since the paper remaining amount display device of the present invention is simply engaged with a moving pin and an elongated slot, the structure can be simple and inexpensive.

が容易となる。 Furthermore, the scale length of the indicator can be easily changed over a wide range by simply changing the inclination angle of the elongated slot provided in the indicator member.
For example, as schematically shown in FIG. 3, if the inclination angle of the elongated slot 8A of the indicator member 6A is increased, the vertical stroke L of the paper feed tray will be increased.
When the indicator scale W 1 becomes smaller and the inclination angle of the elongated slot 8B of the indicator member 6B becomes smaller as shown schematically in FIG. 4, the indicator scale length W 2 becomes larger with respect to the vertical stroke L of the paper feed tray. Become. Generally, the greater the angle of inclination of the elongated slot, the easier it will be to translate horizontally.
