133.Holding tank 1325, holding tank 1325 are offered on the end wall 1324 of the one end of rotation force transmission element 132 far from pushing piece 131
It extends internally along the axis for being parallel to rotary force reception head 12, spring 133 is set in rotary force and receives outside head 12, spring 133
First end be connected on the bottom wall of holding tank 1325, the second end of spring 133 is connected on the end wall 114 of accommodating chamber 111.
Referring to Fig. 7 and Figure 14 to Figure 17, the installation to handle box in the present embodiment below and the process work of taking-up are retouched as follows
It states.Handle box is removably mounted in the box storehouse of imaging device, and imaging device is printer, the roof in box storehouse in the present embodiment
Or driving is raised (not shown) towards being provided on the side wall of insert port, driving protrusion is located at the mobile road of the second forced section 1911
On diameter, the movement routine of the second forced section 1911 refers to the road that the second forced section 1911 is passed through when handle box is installed in box storehouse
On diameter.Transmission shaft 100 is arranged on the side wall of one end of the length direction in box storehouse, and transmission shaft 100 is used to provide rotation to handle box
Turn driving force.
The installation process of handle box includes the following steps.
Firstly, by the box storehouse of handle box insertion printer, it is defeated before the second forced section 1911 with driving projection contacts
Arm 17 is located in engaging groove 1322 out, and output arm 17 is located at the position engaged with engaging groove 1322.
Then, handle box is pushed forward, and with after driving projection contacts, the second forced section 1911 is driving the second forced section 1911
It moves driving push rod 191 under the reaction force of protrusion to move along the extending direction of guiding groove 182, the inclined-plane 193 of push rod 191 and the
One forced section 1300 abuts, and applies to the first forced section 1300 along the axial direction for being parallel to rotary force reception head 12 and backwards to rotation
Turn the directed force F that power receives the dog end of head 12, pushing piece 131 pushes the leading along transmission gear 11 of rotation force transmission element 132
Side to extending direction to the separate dog end in portion 112 is mobile, 133 forced compression of spring.
Then, output arm 17 comes out from engaging groove 1322 under the guidance of guide wall 1303, at this point, output arm 17 is revolving
The projection for turning the axis that power receives head 12 does not coincide with rotation force transmission element 132 in the projection that rotary force receives the axis of head 12
Position, i.e. output arm 17 is located at the position isolated with engaging groove 1322, and rotary force receives head 12 and exists relative to force transfer mechanism
It being freely rotated in the circumferential direction of force transfer mechanism, torsional spring 151 limits rotary force and receives the angle that head 12 rotates in the circumferential, thus
When the transmission shaft 100 of dog 124 and printer, which occurs to support, touches interference, rotary force reception head 12, which turns an angle, to be kept away
It allows, so that rotary force, which receives head 12, swimmingly to be engaged with the transmission shaft of printer 100, ensure that handle box falls machine
Smoothness.
Then, rotary force receives head 12 and engages with transmission shaft 100.
Then, continue to push handle box, the second forced section 1911 is separated with driving protrusion, and push rod 191 is in 192 elasticity of tension spring
It is moved under the action of restoring force along the extending direction of guiding groove 182, driving mechanism discharges the first forced section to pushing piece 131
1300 active force.Meanwhile under the action of 133 elastic restoring force of spring, spring 133 pushes rotation force transmission element 132 and band
Dynamic pushing piece 131 is moved along the guide part 112 of transmission gear 11 to close to dog end side.
Then, output arm 17 enters in engaging groove 1322 under the guidance of guide wall 1303, and abuts with limited wall 1301,
Output arm 17 is located at the position engaged with engaging groove 1322 at this time.Handle box falls machine completion.
Handle box is installed to after printer, after rotary force receives the rotary driving force that head 12 receives the transmitting of transmission shaft 100
Transmission gear 11 is passed to by rotation force transmission element 132, so that transmission gear 11 be driven to rotate.
The installation process of process and handle box that handle box takes out from printer on the contrary, be no longer described in detail herein.
Therefore be inserted into handle box in the box storehouse of printer, it is defeated before the second forced section and driving projection contacts
Arm is located in engaging groove out, and output arm is located at the position engaged with engaging groove.Then, handle box, the second forced section are pushed forward
After contact driving protrusion, applies active force to the first forced section and force transfer mechanism is pushed to receive head along rotary force is parallel to
The position that output arm is separated with engaging groove is moved axially to, rotary force receives head relative to force transfer mechanism in force transfer mechanism
It is freely rotated in circumferential direction.Rotary force receives head and engages with transmission shaft.Then, continue to push handle box, the second forced section and driving
Protrusion separation, the active force that driving mechanism is applied to the first forced section disappear, and spring driving force transfer mechanism restores to output arm
The position engaged with engaging groove, handle box fall machine completion.Head is received relative to force transfer mechanism in force transfer mechanism in rotary force
Circumferential direction on the position that is freely rotated, it can be achieved that the dog that rotary force receives head is swimmingly engaged and is taken off with printer transmission shaft
From so that handle box be made successfully to be fitted into printer or swimmingly take out from printer.
Finally it is emphasized that the above is only the preferred embodiment of the utility model, it is practical new to be not limited to this
Type, for those skilled in the art, the utility model can have various change and change, all essences in the utility model
Mind and principle within, any modification, equivalent substitution, improvement and etc. done, should be included in the protection scope of the utility model it
It is interior.
