In these drawings, the drive unit 12 is provided with a base plate 25 attached to a stud 26 erected on the bottom plate 2, and the base plate 25 is bent in a pair so as to face each other. The shaft support portions 25a and 25a are provided with an attachment portion 25b that is bent so as to be inclined and to which the antenna unit 13 is attached, and an attachment portion 25c to which the above-described light receiving element 23B is attached.

  A shaft 27 serving as a rotation center of the shutter 11 is rotatably supported by the shaft support portions 25a and 25a. A motor 28 is fixed to the base plate 25 via a bracket 29, and a motor gear 30 is attached to the output shaft 28a as shown in FIG. A gear 31 is rotatably supported by the bracket 29 and meshes with the motor gear 30. A small-diameter gear 31a is integrally provided. A gear 32 is rotatably supported by the bracket 29 and meshes with the small-diameter gear 31a. The pinion 32a is integrally provided.

  As shown in FIG. 1, the shutter 11 is provided with both side portions 11 </ b> A and 11 </ b> B that are formed to be opposed to each other at both ends so as to be formed in a U-shaped cross section. Each end of the shaft 27 is axially attached to the small holes 11b and 11b formed in the lower end of 11B. Therefore, the shutter 11 is supported so as to be rotatable between a position covering the mounting portion 15a shown in FIG. 6 and a position opening the mounting portion 15a shown in FIG. Yes. A support plate 35 formed in a substantially square shape is attached to one side portion 11A so that the surfaces of the support plate 35 are in contact with each other. As shown in FIG. 6, spring latching portions 35a, 35a are cut and raised.

  Reference numeral 36 denotes a rack formed in an arc shape with the shaft 27 as the center. A pair of long holes 36a and 36a are provided at both ends, teeth 36b are formed on the lower surface, and a cross section is formed at the central portion of the upper surface. A V-shaped recess 36c is formed. The rack 36 is inserted through the long holes 36a and 36a and is screwed into the support plate 35 through bolts 37 and 37, with the shaft 27 being the center of rotation, and only a predetermined range in the clockwise and counterclockwise directions in the figure. The support plate 35 is rotatably supported. Further, the rack 36 is pulled in opposite directions by the tensile force of the pair of tension coil springs 38A and 38B suspended between the both ends of the rack 36 and the spring latching portions 35a of the support plate 35. Thus, the rack 36 is held by the support plate 35 in a state where the rotation is restricted, that is, in a stopped state. In this state, the teeth 36b of the rack 36 and the pinion 32a are engaged with each other, and the shutter 28 rotates the shaft 27 via the rack 36 by driving the motor 28 in the forward and reverse directions as will be described later. It rotates in the central and counterclockwise directions.

  Reference numeral 39 denotes a leaf spring for detection whose base end is attached to the support plate 35, and a convex portion 39a having a V-shaped cross section engaging with the concave portion 36c of the rack 36 is formed at the swing end portion. A limit switch 40 is fixed to the support plate 35 and detects a slight rotation of the rack 36. That is, when the rack 36 is held by the tension coil springs 38A and 38B and is not moved with respect to the support plate 35 (hereinafter, this position is referred to as a neutral position), the plate spring for detection is used. The convex portion 39 a of 39 is engaged with the concave portion 36 c of the rack 36. From this state, when the rack 36 moves slightly in the clockwise / counterclockwise direction with the shaft 27 as the rotation center, the convex portion 39a of the leaf spring 39 for detection is disengaged from the concave portion 36c. In order to ride on the upper surface, the limit switch 40 is actuated by the swinging end portion of the leaf spring 39 for detection. When the limit switch 40 is activated, the driving of the motor 28 is stopped. Therefore, the concave portion 37c of the rack 36, the leaf spring 39 for detection, and the limit switch 40 constitute a movement detecting means 41 that detects movement from the neutral position of the rack 36.

  As shown in FIG. 1, the antenna unit 13 is provided with a bracket 42 formed in a frame shape to be attached to the attachment portion 25b of the base plate 25. The bracket 42 is provided with a rectangular through hole 43a. The antenna substrate 43 is fixed. Therefore, when the bracket 42 is attached to the attachment portion 25b of the base plate 25, the antenna substrate 43 is positioned below the placement portion 15a so as to be parallel to the placement portion 15a as shown in FIG. In this state, data communication is performed in a non-contact state between an antenna unit (not shown) formed on the antenna substrate 43 and the medium 7 in the wallet 8 placed on the placement unit 15a. Data transmitted to the antenna substrate 43 is read / written by data processing means (not shown).

  Further, the through hole 43a of the antenna substrate 43 positioned below the mounting portion 15a corresponds to the light transmitting portion 15b of the mounting portion 15a, and the light 23C emitted from the light emitting element 23A as described above is obtained. As shown in FIG. 2, after passing through the light transmitting portion 15b of the mounting portion 15a, it passes through the through hole 43a of the antenna substrate 43 and is received by the light receiving element 23B. The light emitting element 23A and the light receiving element 23B are provided at positions sufficiently separated from the antenna substrate 43 so as to be positioned outside the region of the magnetic field generated from the antenna portion of the antenna substrate 43. Therefore, since the light emitting element 23A and the light receiving element 23B are not affected by the magnetic field generated from the antenna substrate 43, the light emitting element 23A and the light receiving element 23B do not malfunction. For this reason, it is possible to accurately detect that the wallet 8 containing the medium 7 is placed on the placement portion 15a by the light emitting element 23A and the light receiving element 23B.

  Next, the processing operation of the medium 7 in the processing apparatus 1 configured as described above will be described. As shown in FIGS. 2 and 7, the shutter 11 is positioned in advance at a position where the placement unit 15 a is opened. In this state, the wallet 8 in which the medium 7 is put by hand from the opening 6a of the housing 6 is inserted into the housing 6 and placed on the placement portion 15a. When the wallet 8 is placed on the placement portion 15a, the wallet 8 is detected by the light emitting element 23A and the light receiving element 23B, so the motor 28 is driven in the forward direction and the shutter 11 covers the placement portion 15a. Start moving to.

  At this time, if the hand holding the wallet 8 is still inserted in the housing 6, the first and second infrared transmitters 21A, 22A and the first and second infrared receivers 21B, 22B Since the hand is detected, the drive of the motor 28 in the positive direction is stopped. For this reason, since the shutter 11 does not accidentally cover the mounting portion 15a while the hand is inserted in the housing 6, the shutter 11 is driven by the hand hitting the shutter 11 to be closed. It is possible to prevent a load from being applied to the drive unit 12 that is present.

  On the other hand, it is confirmed by the first and second infrared transmitters 21A and 22A and the first and second infrared receivers 21B and 22B that the hand holding the wallet 8 is pulled out of the housing 6. Then, the motor 28 is driven in the positive direction. When the motor 28 is driven in the forward direction, the motor gear 30 rotates counterclockwise in FIG. 7, so that the gear 31 engaged therewith rotates in the clockwise direction. Accordingly, since the gear 32 that meshes with the small diameter gear 31a of the gear 31 rotates counterclockwise, the pinion 32a also rotates integrally counterclockwise, and the rack 36 having teeth 36b that mesh with the pinion 32a is connected to the shaft 27. Is rotated counterclockwise around the center of rotation.

  When the rack 36 is rotated counterclockwise, the shutter 11 is integrated with the shaft 27 as the center of rotation through a pair of tension coil springs 38A and 38B holding the rack 36 and the support plate 35. It rotates counterclockwise. At this time, the convex portion 39 of the leaf spring 39 for detection engages with the concave portion 36 c of the rack 36, and the neutral position of the rack 36 is held by the elastic force of the leaf spring 39, so that the shutter 11 is counterclockwise. Is reliably rotated.

  If the shutter 11 is intentionally or mistakenly prevented from rotating by hand or the like, only the rack 36 rotates slightly counterclockwise against the tensile force of one of the tension coil springs 38B as shown in FIG. To do. Therefore, the convex portion 39 a of the detection leaf spring 39 is disengaged from the concave portion 36 c of the rack 36 and rides on the upper surface of the rack 36, so that the limit switch 40 is moved by the swing end portion of the detection leaf spring 39. Operate. When the limit switch 40 is activated, the driving of the motor 28 is stopped and an alarm means (not shown) is activated. As described above, if the movement of the shutter 11 is intentionally or mistakenly prevented by hand or the like, the driving of the motor 28 is stopped and the rotation of the shutter 11 is stopped. Absent. Moreover, since the response by the administrator who manages the processing apparatus 1 is accelerated by the operation of the alarm means, not only the convenience for the administrator is improved, but also the service to the user can be prevented from being lowered.

  On the other hand, when the shutter 11 rotates counterclockwise about the shaft 27 as a rotation center, the placement portion 15a is covered by the shutter 11 as shown in FIG. In this state, data communication is performed in a non-contact state between the antenna portion (not shown) of the antenna substrate 43 and the medium 7 placed in the wallet 8 placed on the placement portion 15a. Data transmitted to the substrate 43 is read and written by data processing means (not shown).

  When the processing of the data recorded on the medium 7 is completed, the motor 28 is driven in the reverse direction, and the motor gear 30 is rotated in the clockwise direction in FIG. 6, so that the gear 31 engaged therewith is rotated in the counterclockwise direction. Accordingly, since the gear 32 that meshes with the small-diameter gear 31a of the gear 31 rotates in the clockwise direction, the pinion 32a also rotates integrally in the clockwise direction, and the rack 36 having the teeth 36b that mesh with the pinion 32a rotates the shaft 27. It rotates clockwise as the center of movement.

  By rotating the rack 36 in the clockwise direction, the shutter 11 is integrally formed with the shaft 27 as the center of rotation through the pair of tension coil springs 38A and 38B holding the rack 36 and the support plate 35. And the upper part of the mounting portion 15a is opened as shown in FIG. Therefore, the user inserts his / her hand into the housing 6 and takes out the wallet 8 placed on the placing portion 15a.

  In the present embodiment, the mode in which the medium 7 placed in the wallet 8 is indirectly placed on the placement unit 15a has been described as the mode of placement on the placement unit 15a. As a placing method, a form in which a portable terminal on which the medium 7 is mounted may be placed, or a form in which the medium 7 is placed directly on the placing portion 15a may be employed.
