Description

  The present invention relates to an electronic device with a card insertion slot such as a digital tachograph mounted on a vehicle.

  For example, in in-vehicle electronic devices such as digital tachographs and automatic toll collection systems (ETC: Electronic Toll Collection System) in-vehicle devices, memory cards and IC cards, which are information storage media, are mounted on the front panel (exterior panel) of the device body. Some of them have a card insertion slot for inserting the information storage medium card.

  As such an electronic apparatus with a card insertion slot, a digital tachograph described in Patent Document 1 is known, and FIG. 4 shows an appearance of a conventional digital tachograph 100 described in the same document.

  The digital tachograph 100 has a front panel 102 equipped with various switches on the front surface of a main body case 101, and has a card insertion slot 103 for inserting an information storage medium card C in the front panel 102.

  When the card C is inserted into the card insertion slot 103, the slide button 104 covers a part of the card insertion slot 103 with the force of a spring (not shown), and the card C cannot be removed even if the ejection button 105 is operated. ing. Then, the writing of information to the card C is started in response to the operation of the end button 106.

  Further, when the card C is removed, the card C is removed from the insertion slot 103 by pressing the ejection button 105 while holding the slide button 104 shifted to the left side of the front panel 102 so as not to reach the card insertion slot 103. It can be discharged.

By the way, in this digital tachograph 100, the card insertion slot 103 provided on the front panel 102 is always exposed to the outside. This prevents the tachograph from being mistakenly operated, and thus has a problem of weak protection. Such a problem can also occur in devices other than digital tachographs.

  In order to solve such a problem, the present inventors have provided a slide type shutter 113 for opening and closing the card insertion slot 112 on the front side of the front panel 111 of the device main body 110 as shown in FIG. When the card C was not inserted or removed, a digital tachograph was proposed in which the card insertion slot 112 was shielded by the shutter 113 (not disclosed).

  In the case shown in FIG. 5, the sliding direction of the shutter 113 is the left-right direction indicated by the arrow A. When the card C is not inserted or removed, the shutter 113 is moved to the left as shown in FIG. Slide to cover the card insertion slot 112, and when the card C is inserted or removed, as shown in FIG. 5B, the shutter 113 slides to the right side to open the card insertion slot 112. Yes.

  In this case, a spring is used as a power source for opening the shutter 113, and the lock at the closed position is released, so that the shutter 113 moves to the open side by the force of the spring so that the shutter 113 hits the stopper and stops. Devised and examined.

  However, in the course of the study, the shutter 113 and the stopper are molded with a hard resin, so when the hard resin shutter 113 and the stopper are collided as they are, there is a possibility that a collision sound may be produced. .

  In view of the above circumstances, an object of the present invention is to provide an electronic device with a card insertion slot that can prevent generation of unnecessary collision noise.

  The electronic device with a card insertion slot of the invention of claim 1 is provided with a card insertion slot for inserting an information storage medium card into the interior of the device body on the exterior panel of the device body. When a shutter for opening and closing the card insertion slot is provided slidably along the exterior panel, and when the shutter is urged to the open side between the device body and the shutter, the lock to the closed position is released And an urging member for moving the shutter to a position where the card insertion slot is opened. When the shutter is moved to the open side by the force of the urging member, A stopper that stops the shutter at a fixed position by abutting against the abutting portion is provided, and the stopper and the shutter abut against at least one of the stopper or the shutter. In contact with the mating cushion member to be elastically deformed is characterized in that it is provided.

  The invention of claim 2 is the electronic device with a card insertion slot according to claim 1, wherein the shutter has its upper and lower end edges engaged with a rail formed in the device body, It is characterized by being slidable in the left-right direction along the rail.

  A third aspect of the present invention is the electronic device with a card insertion slot according to the first or second aspect, wherein a sliding action of the shutter is caused by a frictional resistance by slidingly contacting the exterior panel on the back surface of the shutter. It is characterized in that a spring member for imparting is provided.

  A fourth aspect of the present invention is the electronic device with a card insertion slot according to any one of the first to third aspects, wherein the biasing member is formed of a coil spring and is disposed on the back side of the shutter. It is characterized by that.

  According to the first aspect of the present invention, it is possible to reduce the collision noise (abnormal noise) between the stopper and the shutter when the shutter is opened by the force of the urging member by the action of the cushion material.

  According to the second aspect of the invention, since the upper and lower end edges of the shutter are engaged with the rail, the shutter can be stably slid with a simple structure while preventing the shutter from dropping off.

  According to the invention of claim 3, since the moving speed of the shutter can be lowered by the damper action, it is possible to further reduce the collision sound when the shutter is opened. In addition, since the shutter is moved slowly, a profound feeling and a high-class feeling can be given.

  According to invention of Claim 4, the coil spring which is an urging | biasing member can be arrange | positioned in the position which cannot be seen from a front surface, and appearance is not impaired.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a partial perspective view of a front portion of a digital tachograph according to an embodiment as viewed from below. 2A is a front view of a portion II in FIG. 1, FIG. 2B is a diagram showing a comparative example in the case where there is no cushion material with respect to FIG. 2A, and FIG. FIG. 3B is a diagram showing a comparative example in the case where there is no leaf spring as compared with FIG. 3A.

  As shown in FIG. 1, an apparatus body 1 of this digital tachograph is composed of an upper case 2 and a lower case 3 that house digital tachograph circuits, etc., and a front panel (exterior panel) that covers the front openings of the upper case 2 and the lower case 3 4). The front panel 4 is provided with a card insertion slot 5 for inserting an IC card (information storage medium card) C into the apparatus main body 1, and a shutter 6 for opening and closing the card insertion slot 5 on the front surface of the front panel 4. Is slidable in the left-right direction (arrow A direction) along the front panel 4.

  The shutter 6 has engagement edge portions (upper and lower edge portions) 6b and 6c at the upper end and lower end of the front wall 6a, and these engagement edge portions 6b and 6c are connected to the front end of the flange portion 2a of the upper case 2. By engaging the rail groove 2b provided on the lower surface and the rail groove 3b provided on the lower surface of the front end of the lower case 3, it is slidable in the left and right directions along the rail grooves 2b and 3b. The rail grooves 2b and 3b are prevented from coming out. Thereby, the shutter 6 can be stably slid with a simple structure.

  Further, between the device main body 1 and the shutter 6, both ends are engaged with a hook 3 d provided on the lower case 3 and a hook 6 d provided on the lower end of the shutter 6, whereby the shutter 6 is opened (see FIG. 1). A coil spring (biasing member) 7 for urging the inner right side) is stretched. The coil spring 7 moves the shutter 6 to a position where the card insertion slot 5 is opened when the lock to the closed position is released. The coil spring 7 is arranged so as to be hidden behind the shutter 6, and looks good. It is designed not to be damaged.

  In addition, as shown in FIG. 2A, the shutter 6 is moved to the open side (right side) as indicated by the arrow A by the force of the coil spring 7, as shown in FIG. A stopper 3s that stops the shutter 6 at a fixed position by abutting against the right end surface (contact surface) 6s on the shutter 6 side when it moves is provided. In particular, in this case, a cushion material 8 that comes into contact with the shutter 6 and elastically deforms is provided near the stopper 3s (lower side in the illustrated example) before the stopper 3s and the shutter 6 abut against each other. That is, the cushion material 8 protrudes toward the shutter 6 than the stopper 3s. The cushion material 8 may be anything as long as it is an elastic member, and rubber, elastomer, urethane foam, spring, or the like can be used.

  Further, as shown in FIG. 3A, the curved portion is in sliding contact with the outer surface of the front panel 4 on the back surface of the shutter 6, thereby imparting a damper action by frictional resistance to the sliding operation of the shutter 6. A letter-shaped leaf spring (spring member) 9 is provided. Without this leaf spring 9, as shown in FIG. 3B, there is a gap d between the shutter 6 and the front panel 4, so the shutter 6 moves quickly with almost no resistance. Due to the sliding resistance by the leaf spring 9, a damper action is given to the movement of the shutter 6, and the moving speed of the shutter 6 is restricted.

  Next, the operation will be described.

  The shutter 6 is moved to the right side in FIG. 1 by the force of the coil spring 7 when the lock (not shown) is released, and finally hits the stopper 3s and stops, but before that, as shown in FIG. By hitting the material 8 first, it reaches the final position while absorbing the impact. Therefore, the collision sound (abnormal noise) between the stopper 3s and the shutter 6 can be reduced. Incidentally, when there is no cushion material 8 as shown in FIG. 2 (b), the hard resin material shutter 6 and the stopper 3s collide with each other. By providing the cushion material 8 as in a), it is possible to prevent the occurrence of a collision sound and improve the quality.

  In this case, the cushion material may be directly attached to the contact surface of the stopper 3s with respect to the shutter 6, but instead, the cushion material 8 is provided separately from the stopper 3s so as to be adjacent to the stopper 3s. However, it is possible to stop and finally hit the stopper 3 s while elastically deforming the cushion material 8, so that the accuracy of the stop position can be obtained.

  Further, when the shutter 6 is slid, the damper action by the leaf spring 9 acts, so that the moving speed of the shutter 6 can be reduced, and the collision sound when the shutter 6 is opened can be further reduced. Moreover, since the shutter 6 can be moved slowly, a profound feeling and a high-class feeling can be given.

  In the above embodiment, the cushion material 8 is provided on the stopper 3s side. However, the cushion material 8 may be provided on the shutter 6 side or on both sides.
