When the ear piece 240 of the smartphone 200 is slidably inserted into the chute 130, the ear piece 240 presses the other side 134b of the elastic piece 134, so that the other end of the elastic piece 134 is close to the opposite plate 132, and the elastic piece 134 is lifted to generate elastic force, As a result, the elastic piece 134 (pressing mechanism 133 ) presses the ear piece 240 against the back of the backplane 110 , thereby fixing the smartphone 200 on the backplane 110 more stably.

The sliding restricting portion 140 is a limiting portion that restricts the sliding of the smartphone 200 . The slide restricting portion 140 is provided on the other end side (upper side in FIG. 1 ) of the pair of sliding grooves 130 so as to extend in the width direction of the back plate 110 , and specifically, the side provided on the back surface of the back plate 110 is short. edge (upper edge in Figure 1). In addition, the sliding restriction portion 140 is matched with the single ear piece 250 of the smartphone 200 . The sliding of the smartphone 200 toward the upper side relative to the back panel 110 can be restricted by matching the sliding restricting portion 140 with the single ear piece 250 .

A storage space S for storing the smartphone 200 is formed by the pair of sliding grooves 130 , the single sliding restricting portion 140 , and the back surface of the back plate 110 . Since the pair of sliding grooves 130 and the single sliding restricting portion 140 are respectively disposed on a pair of long edges on the back of the back plate 110 and a short edge on one side of the back of the back plate 110 , almost the entire back of the back plate 110 can be used as the storage space S The slidable smartphone 200 is accommodated. The sliding storage action is faster, and the three-point fixing makes the connection between the back panel 110 and the smartphone 200 more stable.

As shown in FIG. 6 , like the chute 130 , the slide restricting portion 140 includes an upright plate 141 and an opposing plate 142 . The upright plate 141 is vertically fixed to the back of the back plate 110 . The opposing plate 142 is formed at the top end of the upright plate 141 and is opposite to the back plate 110 in parallel.

In order to store the smartphone 200 stably, a pressing mechanism 143 is provided on one side (inside) of the opposing plate 142 facing the back plate 110 . The pressing mechanism 143 presses the single ear piece 250 of the smartphone 200 against the back of the back panel 110 . In this way, the looseness between the external lens assembly 100 and the smartphone 200 can be avoided, resulting in the change of the flange distance between the lens 120 and the smartphone 200 .

As shown in FIG. 6 , in the present embodiment, the pressing mechanism 143 in the slide restricting portion 140 is different from the pressing mechanism 133 , and the pressing mechanism 143 includes a pressing piece 144 and a spring 145 . The pressing piece 144 is used for pressing the ear piece 250 . The pressing piece 144 includes one end surface 144 a facing the opposing plate 142 , another end surface 144 b serving as a pressing surface facing the back surface of the back plate 110 , and an inclined surface 144 c facing the back surface of the back plate 110 . The inclined surface of the inclined surface 144c faces the other end side (the lower side in FIG. 1 ), that is, the insertion side of the smartphone 200 . The provision of the inclined surface 144c facilitates the insertion of the tab 250 . In the natural state of the spring 145, the minimum distance between the other end surface 144b of the pressing piece and the back of the back plate 110 must be smaller than the thickness of the ear piece 250, so as to ensure that when the smartphone 200 is inserted into the external lens assembly 100, the ear piece 250 can interfere with It is further pressed to the other end surface 144b of the pressing piece.

The spring 145 is used to connect the pressing piece 144 to the opposing plate 142 . One end of the spring 145 is fixed to the bottom surface of the spring receiving hole 142 a formed in the opposing plate 142 , and the other end of the spring 145 is fixed to one end surface 144 a of the pressing piece 144 . Thereby, the pressing piece 144 is supported by the opposing plate 142 by the spring 145 .

When the spring 145 is in a natural state, that is, when the spring 145 is in an uncompressed state, the pressing piece 144 is separated from the opposing plate 142 . First, when the ear piece 250 of the smartphone 200 is slidably inserted into the sliding restricting portion 140 , the ear piece 250 presses the inclined surface 144 c of the pressing piece 144 to compress the spring 145 .
