Description

  The present invention relates to an ETC (Electronic Toll Collection) device.

JP-A-2005-321619

  2. Description of the Related Art ETC on-board devices (for example, Patent Document 1) that have been widely used in recent years employ a slide type or push type eject button for taking out an ETC card from a casing. Inside the housing is a carrier for the ETC card at the time of mounting / discharging, and a sliding member that is biased in the discharging direction by the spring, and the sliding member is held in the mounting position against the biasing force of the spring, and the state And a lock member that moves the slide member in the ejecting direction together with the mounted ETC card by releasing the engagement with the slide member.

  The movement path of the lock member relative to the slide member occurs in a direction that intersects the card ejection direction by the slide member (that is, in the lateral direction), so if the eject button is slid, the movement of the eject button is directly transmitted to the lock member. it can. However, in the case of the push button type, it is necessary to convert the operation stroke of the push button generated in the front-rear direction into a movement in the horizontal direction and transmit it to the lock member. That is, in addition to the slide member and the lock member, a transmission member that performs the conversion is required. In this case, conventionally, when the first spring for biasing the slide member in the ejecting direction and the slide member are moved together with the card to the mounting position, the lock member is moved to the engagement position with the slide member. The three springs of the second spring and the third spring for biasing the discharge button to the pressing standby position are used, and there is a disadvantage that an increase in the number of parts is unavoidable.

  An object of the present invention is to provide an ETC vehicle-mounted device that can reduce the number of necessary springs (elastic members) and can be configured at low cost while the eject button is a push type.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the ETC on-board device of the present invention is:
A housing with an open card slot;
It has a card receiving part that receives the front edge of the card inserted in the case from the card slot, and is inserted in the case with the side far from the card slot in the insertion direction as the front side and the near side as the back side. A slide member provided so as to be able to advance and retreat with the card between a card mounting position located on the front side in the direction and a card ejection position located on the rear side,
A first elastic member that elastically deforms as the slide member moves to the card mounting position, and biases the slide member toward the card discharge position by its elastic return force;
A lock member-side engagement portion is mounted at a position separated from the axis by a predetermined length in the turning radius direction along a card surface within the housing so as to be pivotable about a predetermined axis, and the slide member is a card. By engaging the slide member side engagement portion and the lock member side engagement portion on the slide member in a state where the slide member is located at the mounting position, the slide member is locked against the elastic restoring force by the first elastic member. A lock member that releases the engagement state between the slide member side engagement portion and the lock member side engagement portion by turning in a predetermined unlocking direction from the lock holding position,
An eject button that is pressed against the housing in a direction that matches the card insertion direction into the card slot;
The eject button and the lock member are coupled, and the forward / backward movement of the eject button is disengaged from the lock member in the same manner as the engagement position where the slide member side engagement portion and the lock member side engagement portion are engaged. A transmission member for transmitting while converting to a turning motion in both forward and reverse directions to and from the disengagement position;
And a second elastic member that elastically urges the lock member to pivot to the engagement position via the transmission member in a direction in which the eject button is pushed back.

  The ETC in-vehicle device having the above-described configuration operates as follows with the attachment / detachment of the card. First, when the slide member is in the discharge position, the lock member turns in the unlocking direction, and the lock member side engaging portion and the slide member side engaging portion are in a disengaged state. When the card is inserted into the card slot in this state, the card is inserted into the card receiving portion at the front end of the slide member (note that the side far from the card slot in the insertion direction is defined as the front side and the near side is defined as the rear side). The front end edge hits, and the slide member moves forward together with the card while elastically deforming the first elastic member. If the turning direction of the lock member is defined as the positive direction from the engagement position to the engagement release position, when the slide member reaches the card mounting position, the eject button is retracted by the urging force of the second elastic member, The reverse stroke is transmitted to the lock member by the transmission member while being converted into a reverse turning stroke. As a result, the lock member moves to the engagement position, and the slide member is held in the mounting position together with the card. When the eject button is pressed in this state, the forward stroke of the eject button is transmitted to the lock member by the transmission member while being converted into a forward turning stroke. As a result, the lock member moves to the disengagement position, and the slide member moves to the discharge position together with the card by the elastic return force of the first elastic member.

  The gist of the configuration of the present invention is that the transmission member for connecting the eject button and the lock member is engaged with the slide member side engagement portion and the lock member side engagement portion with respect to the lock member for the forward and backward movement of the eject button. It is the point which comprised as a member which transmits, transform | converting into the forward / reverse bidirectional | two-way turning operation | movement between the engagement releasing positions similarly to the engagement positions. As a result, the lock member can be pivoted in conjunction with the forward / backward movement of the eject button without providing an elastic member for moving the lock member to the engagement position with the slide member, thereby ensuring the card mounting / removal operation. it can. That is, although the eject button is a push type, the number of necessary springs (elastic members) can be reduced, and the structure can be reduced.

  The transmission member has one end connected to the eject button, the other end connected to the lock member, and a link member that converts the forward / backward operation force of the eject button into a turning operation force around the axis line and transmits the lock member to the lock member. It can be. A mechanism for rotating the lock member in conjunction with the forward / backward movement of the eject button can be realized by a simple link mechanism, and the configuration can be further simplified.

When the pivot axis position of the lock member is fixed, and the distance between the coupling point on the eject button side of the link member and the coupling point on the lock member side is constant, when both ends of the transmission member are set to normal link coupling, Since the coupling point on the lock member side moves on an arcuate locus centering on the pivot axis of the lock member, the angle of the link member with respect to the forward / backward direction of the eject button must also be changed as the lock member turns. However, this configuration has the following concerns.
(1) The eject button and the link member must be coupled so as to be pivotable, resulting in a complicated structure and an increased number of parts.
(2) The turning angle of the link member corresponding to the forward / backward stroke of the eject button is very small, and it is difficult to ensure the smooth movement of the link member following the turning operation of the lock member.

  However, these concerns can be resolved by configuring as follows. That is, the link member is configured such that one end thereof is coupled to the eject button so as not to be pivotable and moves forward and backward together with the eject button. And, on the other end side of the link member, a positive direction biasing portion that biases the coupled portion on the lock member side in a forward direction of the link member in a direction in which the lock member moves toward the disengagement position, A link member of the coupled portion as the lock member is swung with a reverse biasing portion that biases the coupled portion in a direction in which the lock member moves toward the engagement position when the link member is retracted And a sliding coupling mechanism that couples with the coupled portion while allowing sliding in the turning radius direction.

  That is, the sliding coupling mechanism that constitutes the coupling point between the link member and the lock member has a forward direction biasing portion and a reverse direction biasing portion, thereby allowing the link member to move forward and backward. It can be converted into a swivel movement and transmitted. And, since the coupling point can be slid in the turning radius direction, the turning radius of the coupling point on the lock member side can be changed according to the turning angle of the lock member, and the link member cannot turn with respect to the eject button. Even if they are coupled to each other (that is, even if the direction of advancement / retraction of the link member is fixed so as to coincide with the direction of movement of the eject button), a mechanically consistent operation can be secured.

  The lock member extends from the axis toward the slide member in the turning radius direction and has a first arm portion having a locking member side engagement portion formed at the tip, and a first arm portion extending from the axis toward the link member in the turning radius direction. The two arm portions can be configured to be integrally rotatable. And if the front end side of this 2nd arm part is inserted in the penetration part formed in the link member, the back side inner edge part of a penetration part in the advancing direction of a link member will be a positive direction biasing part, and it will also be a front side inner edge part. The above-described sliding coupling mechanism can be easily realized by forming the reverse direction urging portion.

  In this case, the slide member can be a plate-like member arranged so that the thickness direction coincides with the card, and the slide member side engaging portion can be formed at the rear end edge in the card insertion direction. Thereby, attachment / detachment with the locking member side engaging part and slide member side engaging part which are formed in the 1st arm part front-end | tip can be performed more smoothly.

  Further, in order to effectively utilize the small space in the housing of the ETC on-vehicle device, a slide member is provided on the first side in the width direction of the card mounted in the housing from the card slot, from the side close to the card in the width direction, It is advantageous to arrange the locking members and the link members in this order. In this case, at the rear end edge of the slide member, the slide member side engaging portion is bent back to one plate surface side of the plate-like slide member at the end portion on the side where the lock member is located in the width direction. Protrusions can be formed. The sliding member side engaging portion can be easily formed by bending, and the engaging area of the sliding member side engaging portion can be easily adjusted to a desired value according to the size of the bending portion.

  Specifically, the housing can be formed in a flat box shape, and a plate frame-shaped base member can be assembled in the housing in a form in which the thickness direction is matched. The slide member and the lock member can be arranged on the first plate surface side of the base member, and the link member is arranged so that the width direction coincides with the thickness direction of the base member, and in the width direction of the base member It can be formed in a strip shape extending along the side edge on the first side. By arranging the strip-shaped link member along the side edge in the width direction of the base member, further space saving can be achieved.

  Hereinafter, the operation of the ETC vehicle-mounted device 1 will be described (the turning direction of the lock member 32 is defined as the forward direction from the engagement position EP to the engagement release position RP). FIG. 3 shows the operation when the card is mounted. As shown in state A, when the slide member 31 is in the ejected position, the lock member 32 pivots in the unlocking direction (forward direction), and the lock member side engagement is shown. The joint portion 32e and the slide member side engaging portion 31b are in a disengaged state. Next, when the card EC is inserted into the card slot 4 as in the state B, the front end edge of the card EC hits the card receiving portion 31d at the front end of the slide member 31, and the slide member while elastically deforming the first elastic member 51. 31 moves forward together with the card EC. The slide member 31 is configured so that the end edge in the width direction of the slide member side engagement portion 31b is a corresponding side edge of the lock member 32 by the turning biasing force toward the engagement position EP transmitted to the lock member 32 via the transmission member 33. The first elastic member 51 is slid and moved while being elastically deformed while being slid above.

  Then, as shown in state C, when the slide member 31 reaches the card mounting position MP, the eject button 3 is retracted by the urging force of the second elastic member 52, and its reverse stroke (Δd: a pressing stroke at the time of card ejection is given. Is transmitted to the lock member 32 by the transmission member 33 while being converted into a revolving stroke in the reverse direction. When the slide member 31 reaches the card mounting position MP, the edge in the width direction of the slide member side engaging portion 31b is disengaged from the front end of the side edge of the lock member 32, and the first arm portion 32a of the lock member 32 is caused by the turning biasing force. The locking member side engaging portion 32e at the tip of the head pivots in the forward direction to the engaging position EP that engages with the sliding member side engaging portion 31b. Thereby, the lock member 32 moves to the engagement position EP, and the slide member 31 is held in the mounting position together with the card EC.

  Next, FIG. 4 shows the operation when the card is ejected. That is, when the eject button 3 is pressed in the state C in which the card EC is mounted, the forward stroke of the eject button 3 is transmitted to the lock member 32 by the transmission member 33 while being converted into a forward turning stroke. Thereby, the lock member 32 moves to the engagement release position RP, and the slide member 31 moves to the discharge position together with the card EC by the elastic return force of the first elastic member 51. That is, as the lock member 32 pivots in the reverse direction by the pressing operation of the eject button 3 and the lock member side engaging portion 32e is disengaged from the slide member side engaging portion 31b, the elastic return force of the first elastic member 51 The slide member side engaging portion 31b slides toward the discharge position while sliding the end edge in the width direction on the side edge of the lock member 32.

It is configured as a member that transmits while converting to a forward / reverse bi-directional turning operation between the engaging position EP to be engaged and the disengaging position RP to be disengaged. As a result, the lock member 32 can be turned in both directions in conjunction with the forward / backward movement of the eject button 3 without providing an elastic member for moving the lock member 32 to the engagement position EP with the slide member 31. it can. Thereby, although the eject button 3 is a push type, the number of necessary springs (elastic members) can be reduced.

  Further, as described above, the sliding coupling mechanism 40 constituting the coupling point between the link member 33 and the lock member 32 includes the forward direction biasing portion 33d and the reverse direction biasing portion 33c, so that the link member 33 is provided. The forward / backward movement can be converted into a bidirectional turning movement of the lock member 32 and transmitted. Since the coupling point is configured to be slidable in the turning radius direction, the turning radius of the coupling point on the lock member 32 side can be changed according to the turning angle of the lock member 32, and the link member 33 is ejected. 3 is secured in a mechanically consistent manner even if it is coupled so as not to be pivotable (that is, even if the forward and backward direction of the link member 33 is fixed so as to coincide with the moving direction of the eject button). .
