JP 2012-15951 A

  In the above-described prior art, a spring member is provided for the opening / closing lid, and the spring member always applies an urging force in the opening direction to the opening / closing lid, thereby facilitating the opening operation of the opening / closing lid. Yes.

  However, smoothing of the opening operation by the spring member may not always be sufficient for some reason, such as when the opening / closing lid is relatively heavy or an accessory is attached to the opening / closing lid.

  An object of the present invention is to provide an electronic device capable of sufficiently and reliably performing a smooth opening operation of an opening / closing lid.

  In order to achieve the above object, the present invention provides a casing including a cassette storage portion for storing a cassette, and an opening / closing lid for opening / closing the cassette storage portion, and an urging force in the opening direction with respect to the opening / closing lid. A first spring member to be acted on, a cassette pressing member provided on the cassette storage portion side of the opening / closing lid, a second spring member for applying a biasing force toward the cassette storage portion side on the cassette pressing member, A lock mechanism for maintaining the closed state of the opening / closing lid, and the second spring member with respect to the cassette pressing member when the opening / closing lid is closed in a state where the cassette is not housed in the cassette housing portion. And a pressing mechanism for applying a pressing force in the contraction direction.

  In the present invention, a cassette housing portion for housing a cassette is provided in the housing, and the cassette housing portion is opened and closed by an opening / closing lid. A first spring member is provided for the opening / closing lid, and the opening operation of the opening / closing lid is facilitated by the first spring member always applying an urging force in the opening direction to the opening / closing lid. .

  However, smoothing of the opening operation by the first spring member may not always be sufficient for some reason, such as when the opening / closing lid is relatively heavy or an accessory is attached to the opening / closing lid. Therefore, in the present invention, the cassette pressing member and the second spring member provided for stable storage of the cassette in the cassette storage portion are utilized.

  That is, the cassette pressing member is provided on the cassette housing portion side of the opening / closing lid, and the second spring member applies a biasing force toward the cassette housing portion side to the cassette pressing member. ing. Thus, when the cassette is stored in the cassette storage portion and the opening / closing lid is closed, the cassette storage portion side of the cassette pressing member abuts on the cassette, and the biasing force of the second spring member is applied from the cassette pressing member to the cassette. Since it is transmitted and the cassette is pressed in the direction of the urging force in the cassette storage portion, the cassette is stably stored.

  Here, if the opening / closing lid is closed without storing the cassette in the cassette storage portion, the second spring member is attached anywhere as it is (there is no cassette that contacts the cassette storage portion). It will be in the state where power is not applied. Therefore, in the present invention, a pressing mechanism is provided in order to utilize the second spring member that is idle as described above on the cassette housing portion side of the opening / closing lid. By this pressing mechanism, when the opening / closing lid is closed in a state where the cassette is not accommodated as described above, the pressing force in the contraction direction of the second spring member acts on the cassette pressing member. As a result, the second spring member applies an urging force in the extension direction (that is, the opening direction of the opening / closing lid) against the cassette pressing member against the pressing force. Therefore, in such a closed state, the biasing force in the opening direction of the first spring member always acting as described above and the biasing force in the opening direction of the second spring member derived from the contraction are provided. Are combined and act. Since the biasing forces of the first spring member and the second spring member act in this way, the opening force of the opening / closing lid after unlocking by the lock mechanism is accelerated by the combined biasing force. A smooth opening operation of the opening / closing lid can be performed sufficiently and reliably.

  According to the present invention, a smooth opening operation of the opening / closing lid can be performed sufficiently and reliably.

<Cassette presser mechanism>
Next, the configuration of the cassette pressing mechanism 100 will be described with reference to FIGS. 2, 3, and 5 to 7. In the following, the direction related to the configuration of the cassette pressing mechanism 100 refers to the direction when the cover 6 is closed.

  5 to 7, the cassette pressing mechanism 100 is provided on the back surface of the cover 6 as described above, and is a pressing plate 110 (corresponding to a cassette pressing member) which is a plate-like member formed in a substantially L shape. ). Hereinafter, in the pressing plate 110, the surface on the back side of the cover 6 is referred to as “back surface”, and the surface on the cassette mounting portion 8 side when the cover 6 is closed is referred to as “surface”. The pressing plate 110 includes a plate-like lower portion 112 extending in the short direction (left-right direction) of the cover 6 and a plate-like upper portion 111 extending in the longitudinal direction of the cover 6 (front-rear direction in the closed state). The length of the plate-like upper portion 111 in the longitudinal direction (the front-rear direction when the cover 6 is closed) is slightly larger than the length of the tape cassette 30 in the longitudinal direction. The length in the longitudinal direction (left-right direction) of the plate-like lower portion 112 is slightly larger than the size of the tape cassette 30 in the short direction.

  A prismatic pressing member 101 is erected vertically from the base end side slightly from the distal end portion on the surface of the plate-like upper portion 111. A prismatic pressing member 103 is erected vertically from the distal end side slightly from the base end portion on the surface of the plate-like upper portion 111. A coil spring 108 (corresponding to a second spring member) is disposed at the tip of the back surface of the plate-like upper portion 111. On the other hand, small-diameter shaft pins 107 protrude from both longitudinal ends of the plate-like lower portion 112. A prismatic holding member 102 is erected vertically from the front end of the surface of the plate-like lower portion 112. A coil spring 109 (corresponding to a second spring member) is disposed at the approximate center of the back surface of the plate-like lower portion 112 in the length direction. The pressing members 101 to 103 have substantially the same length of protrusion from the pressing plate 110.

  A pair of support holes 6 </ b> A are provided on both sides of the back surface of the cover 6 in the left-right direction, adjacent to the shaft support side of the cover 6. Each shaft pin 107 of the pressing plate 110 is inserted into the pair of support holes 6A. The pressing plate 110 is engaged with the cover 6 at the tip end side of the plate-like upper portion 111. Thereby, the pressing plate 110 can swing on the back side of the cover 6. The coil springs 108 and 109 are arranged between the back surface of the cover 6 and the pressing plate 110 so that a biasing force to the pressing plate 110 is always applied to the pressing plate 110. Therefore, the pressing plate 110 is always elastically biased toward the surface side of the pressing plate 110 by the coil springs 108 and 109.

  When the cover 6 is closed, the pressing plate 110 presses the pressing members 101 to 103 from above the tape cassette 30 mounted on the cassette mounting portion 8. At this time, the pressing member 101 comes into contact with the corner portion 324 of the tape cassette 30 and presses from above. The pressing member 102 comes into contact with the corner portion 322 of the tape cassette 30 and presses from above. The pressing member 103 abuts on the pressing receiving portion 393 of the tape cassette 30 and presses from above.

  Further, in the present embodiment, the pressure receiving portion 104 is provided in the front portion (in the vicinity of the tip portion of the plate-like upper portion 111 in this example) of the pressing plate 110 with the cover 6 closed. Specifically, the press receiving portion 104 is provided in a portion of the pressing plate 110 that faces the tape drive shaft 98 that is erected on the front portion of the cassette mounting portion 8. The tape drive shaft 98 and the press receiving portion 104 constitute a press mechanism described in each claim, and the tape drive shaft 98 corresponds to a press protrusion. As shown in FIG. 8, the tape drive shaft 98 and the pressure receiving portion 104 face each other with a predetermined clearance when the cover 6 is closed with the tape cassette 30 mounted on the cassette mounting portion 8. It does not come into contact. Further, as shown in FIG. 9, when the cover 6 is closed when the tape cassette 30 is not attached to the cassette mounting portion 8, the tape receiving shaft 104 and the pressure receiving portion 104 are arranged so that By pressing against the tip of 98, the pressing force in the contraction direction of the coil springs 108 and 109 is applied to the pressing plate 110.

<When closing the cover with the tape cassette installed>
That is, when the tape cassette 30 is mounted on the cassette mounting portion 8 and the cover 6 is closed, the tips of the pressing members 101 to 103 on the back surface side of the pressing plate 110 provided on the back surface of the cover 6 are the corner portions of the tape cassette 30. 324, 322 and the holding surface of the press receiving portion 393, respectively, and the downward biasing force of the coil springs 108, 109 is transmitted from the pressing plate 110 to the tape cassette 30 so that the tape cassette 30 is in the cassette mounting portion 8 described above. It is pressed in the direction of the urging force (downward). At this time, the pressure receiving portion 104 does not come into contact with the tape drive shaft 98 because the pressing plate 110 is pressed upward.

<When closing the cover without a tape cassette>
On the other hand, when the cover 6 is closed without mounting the tape cassette 30 on the cassette mounting portion 8, the press receiving portion 104 abuts against the tip of the tape drive shaft 98 and is pressed upward, so that the coil spring is pressed against the pressing plate 110. The pressing force 108, 109 in the contraction direction acts. As a result, the coil springs 108 and 109 exert an urging force in the extending direction (that is, the opening direction of the cover 6) against the pressing plate 110 against the pressing force. Therefore, in such a closed state, the biasing force in the opening direction of the torsion spring 25 always acting as described above and the biasing force in the opening direction of the coil springs 108 and 109 resulting from the contraction are provided. Are combined and act.

<When opening a closed cover without a tape cassette>
Then, by operating the lock release button 24 to release the engagement of the lock piece 21 with the lock mechanism 23, as described above, when opening the closed cover 6 without mounting the tape cassette 30 on the cassette mounting portion 8, When the biasing force in the above opening direction of the torsion spring 25 and the coil springs 108 and 109 acts on the cover 6 together, the opening force of the cover 6 (after unlocking, the cover 6 is moved by the combined biasing force). The opening movement until it is lifted up a little) is accelerated.

<Effect of this embodiment>
As described above, in the present embodiment, the housing 1 </ b> A is provided with the cassette mounting portion 8 that houses the tape cassette 30, and the cassette mounting portion 8 is opened and closed by the cover 6. The hinge portion 22 of the cover 6 is provided with a torsion spring 25, and the torsion spring 25 always applies an urging force in the opening direction to the cover 6, so that the opening operation of the cover 6 is made smooth. .

  However, smoothing of the opening operation by the torsion spring 25 may not always be sufficient for some reason such as the cover 6 being relatively heavy or an accessory being attached to the cover 6. Therefore, in the present embodiment, the pressing plate 110 and the coil springs 108 and 109 provided for stable storage of the tape cassette 30 in the cassette mounting portion 8 are utilized.

  That is, the pressing plate 110 is provided on the cassette mounting portion 8 side of the cover 6, and the coil springs 108 and 109 apply a biasing force toward the cassette mounting portion 8 to the pressing plate 110. It is like that. As a result, when the tape cassette 30 is housed in the cassette mounting portion 8 and the cover 6 is closed, the cassette mounting portion 8 side of the pressing plate 110 contacts the tape cassette 30 and the coil springs 108 and 109 are attached. Since the urging force is transmitted from the pressing plate 110 to the tape cassette 30 and the tape cassette 30 is pressed in the direction of the urging force in the cassette mounting portion 8, the tape cassette 30 is stably stored.

  Here, if the cover 6 is closed when the tape cassette 30 is not housed in the cassette mounting portion 8, the coil remains as it is (because there is no tape cassette 30 with which the cassette mounting portion 8 contacts). The springs 108 and 109 are in a state where no urging force is applied anywhere. Therefore, in this embodiment, in order to utilize the coil springs 108 and 109 that are idle as described above on the cassette mounting portion 8 side of the cover 6, a pressing mechanism (in the above example, the tape drive shaft 98 and the pressure receiving portion 104 is used. ) Is provided. By this pressing mechanism, when the cover 6 is closed in a state where the tape cassette 30 is not accommodated as described above, the pressing force in the contraction direction of the coil springs 108 and 109 acts on the pressing plate 110. As a result, the coil springs 108 and 109 exert an urging force on the pressing plate 110 in the extension direction (that is, the opening direction of the cover 6) against the pressing force. Therefore, in such a closed state, the biasing force in the opening direction of the torsion spring 25 always acting as described above and the biasing force in the opening direction of the coil springs 108 and 109 resulting from the contraction are provided. Are combined and act. Since the biasing forces of the torsion spring 25 and the coil springs 108 and 109 act in this way, the opening operation of the cover 6 after unlocking by the lock mechanism 23 is accelerated by the combined biasing force. The smooth opening operation of the cover 6 can be performed sufficiently and reliably.

  In the present embodiment, in particular, the pressing mechanism is provided on the tape driving shaft 98 that is a pressing protrusion provided on the cassette mounting portion 8 and the pressing plate 110, and the tape cassette 30 is accommodated in the cassette mounting portion 8. And a pressure receiving portion 104 that is pressed against the tape drive shaft 98 when the cover 6 is closed when the cover 6 is closed. Accordingly, the coil springs 108 and 109 can be reliably shortened by the tape drive shaft 98 on the cassette mounting portion 8 side coming into contact with the pressure receiving portion 104.

  In this embodiment, in particular, the tape drive shaft 98 and the pressure receiving portion 104 face each other with a predetermined clearance when the cover 6 is closed with the tape cassette 30 stored in the cassette mounting portion 8. These are arranged so as not to contact each other. As a result, when the tape cassette 30 is stored, the tape drive shaft 98 and the pressure receiving portion 104 are not in contact with each other, and the storage stability of the tape cassette 30 as in the current state is obtained.

  In this embodiment, in particular, the cover 6 pivots around a rotation axis located at the rear end of the housing 1 </ b> A and opens and closes, and the tape drive shaft 98 is located on the front side of the cassette mounting portion 8. The press receiving portion 104 is provided in the front portion of the pressing plate 110. As a result, the tape drive shaft 98 and the pressure receiving portion 104 are brought into contact with each other on the opposite side of the cover 6 on the side of the rotation axis for opening and closing, thereby enabling more effective urging.

  In the present embodiment, in particular, the torsion spring 25 is provided in the rear portion of the housing 1A, and the tape drive shaft 98 is provided in the front portion of the cassette mounting portion 8 so as to receive pressure. The portion 104 is provided in the front portion of the pressing plate 110. As a result, the tape drive shaft 98 and the pressure receiving portion 104 are brought into contact with each other on the side opposite to the torsion spring 25 for opening and closing, whereby the biasing can be performed more effectively.

  In this embodiment, in particular, the housing 1 </ b> A is provided with a lock release button 24 that opens and closes the cover 6 at the front portion thereof, and the tape drive shaft 98 is provided at the front portion of the cassette mounting portion 8. The press receiving portion 104 is provided at a front portion of the pressing plate 110. As a result, the tape drive shaft 98 and the press receiving portion 104 are brought into contact with each other on the lock release button 24 side, whereby the biasing can be performed more effectively.

  In this embodiment, in particular, the tape drive shaft 98 also serves as a pressing protrusion. Thereby, space is saved without providing a new member by making contact with the pressure receiving portion 104 by utilizing the tape drive shaft 98.
