Abstract

PURPOSE:To surely perform a reading operation and to prevent malfunction from occurring by reading a bar code from a card set in a stopping state. CONSTITUTION:When the card 16 is inserted into a recessed part, a first switch 14 is turned on by making the inserted tip part of the card 16 abut with the movable piece 14a of the first switch 14 first. A light emitting diode 20 is lit when the first switch 14 is turned on. When the card 16 is further inserted, a second switch 15 is turned on by the inserted tip part of the card in a state where the first switch 14 is being turned on. The light emitting diode 20 illuminates the inserted tip part of the card 1 inserted to the recessed part via the aperture part 11b of a case 11. Thereby, sufficient quantity of light can be projected on the bar code displayed on the card 16. Furthermore, the second switch 15 detects the presence of the card, and generates a signal. A sensor 21 reads the bar code by the signal.

This barcode reader holder is provided with a reader storage hole having an open end into which the barcode reader is inserted. Also, a gap is formed facing this opening through which a card with a bar code attached can be passed. This barcode reader holder has the advantage that a conventional pen-shaped barcode reader can be used as is. Furthermore, Japanese Utility Model Application Publication No. 63-48268 discloses a recording medium reading device provided with a guide groove for moving a card recording medium. This recording medium reading device runs a part of the card recording medium using the side and bottom portions of a guide groove as a guide, and data is read by a reading section provided inside the guide groove. This reading device is provided with a movement adjusting means for moving the bottom portion in a direction to change the depth of the guide groove. Japanese Utility Model Application Publication No. 64-10856 discloses a bar code reading device in which a single photoelectric sensor and a scanning photoelectric sensor composed of multiple elements are arranged adjacent to each other. In this barcode reading device, a single photoelectric sensor and a scanning photoelectric sensor consisting of multiple elements can receive reflected light from a barcode using a common light source and optical system. It is possible to select and read the light reception signal or the light reception signal of a scanning photoelectric sensor consisting of multiple elements.

The movable piece 14a of the first switch 14 is attached to a position closer to the entrance 19a than the movable piece 15a of the second switch 15. An opening 11 is provided in the bottom wall 11a of the case 11.
A transparent plate 24 is disposed on a support portion 25 provided in the case 11 above the opening 11b. A lens support 27 that supports a lens holder 26 is provided above the transparent plate 24 . The lens support 27 has an opening 2.
A slit 29 is provided to receive the light shielding plate 28 in which the light shielding plate 8a is formed. The opening 28a of the light shielding plate 28 allows only light directed toward the lens holder 26 having a lens (not shown) to pass through. As shown in FIG. 7, the board 12 has a light emitting diode 20 as a light source for the sensor and a bar displayed on the card 16.
A CCD image sensor 21 as a reader for reading the code is provided. CCD image sensor 21 is arranged above lens holder 26. The board 12 has a cover.
The light emitting diode 3 protrudes outward from the hole 13a of 13.
0 is set. When the card 16 is inserted into the recess 17, the insertion tip of the card 16 first touches the first switch 14.
The first switch 14 is turned on by contacting the movable piece 14a. The light emitting diode 20 is turned on when the first switch 14 is turned on. Further, when the card 16 is inserted deeply, the card 16 is inserted with the first switch 14 turned on.
The second switch 15 is turned on by the insertion tip. The light emitting diode 20 illuminates the insertion tip of the card 16 inserted into the recess 17 through the opening 11b of the case 11. As a result, the barcode displayed on the card 16 is irradiated with a sufficient amount of light. When the first switch 14 is turned on and the second switch 15 detects the presence of the card 16, it generates a detection signal. When this detection signal is generated, the CCD image sensor 21 reads the bar code displayed on the card 16. FIG. 8 is a block diagram showing the reading control circuit 32 attached to the board 12. A first switch 14 is connected to each input terminal of the reading control circuit 32.
, a second switch 15, a CCD image sensor 21, and a lock control circuit 31 provided at a different position. Furthermore, the light emitting diodes 20 and 30 and the lock control circuit 31 are connected to each output terminal of the reading control circuit 32. In the above configuration, the read control circuit 32 is operated based on the operation sequence shown in FIG. That is, the process advances from the start 40 to step 41, where the reading control circuit 32
It is determined whether the switch 14 is turned on or not. card 16
is inserted into the recess 17 and the first switch 14 is turned on, the light emitting diode 20 is turned on in step 42. Next, the process proceeds to step 43, where the card 16 is inserted into the recess 1.

If it is inserted deeply into the recess 17 without being pulled out, it is determined in step 44 whether or not the second switch 15 is turned on. When the second switch 15 is turned on, the CCD image sensor 21 is activated and the bar code displayed on the card 16 is read (step 45). Thereafter, the light emitting diode 20 is turned off (step 46). Subsequently, in step 47, the read control circuit 32 determines whether the read data is predetermined or not, and if the data is predetermined, it sends an output to the lock control circuit 31. For example, a lock device (not shown) is unlocked. When the lock device is unlocked, a signal for detecting unlocking is provided from the lock control circuit 31 to the reading control circuit 32. As a result, the light emitting diode 30 lights up for a certain period of time to notify that the lock device has been unlocked. Next, when the first switch 14 is turned off in step 49, the operation sequence ends. If the first switch 14 is turned off without the second switch 15 being turned on in step 43, the light emitting diode 20 is turned off in step 50, resulting in a return. In this embodiment, if only the part of the card 16 on which the bar code is displayed is inserted into the entrance 19a, the CCD image sensor 21 will read the bar code displayed on the card 16. Therefore, the reading device 10 can be made thin. The embodiments of this invention are not limited to the above embodiments and can be modified. For example, the first
Other optical or magnetic detection sensors may be used instead of the switch 14 and the second switch 15. Also,
The output of the read control circuit 32 can also be connected to devices other than the lock control device.
