Abstract

ABSTRACT OF THE DISCLOSURE
A cover-equipped camera includes a cover movable bet-ween right and left at the front of a camera body to shield or expose its lens and finder, and a fixed cover with and from which the movable cover is contacted or released respectively.
The opening and closing cover is effected by a mechanism which includes a sliding guide member integral with the cover, and sliders extending from the camera body. The movable cover is guided and slid with the sliders fitted into slots formed in the sliding guide member. When the movable cover is to be opened for exposure, a lock lever is released by the action of an operating lever to quickly open the movable cover. The movable cover is also maintained open by a magnetic force. The cover-equipped camera can achieve protection and dust-free effects, has excellent quick shuttering capacity, and can take photos without failure.

Description

The present invention rela-tes to a cover-equipped camera and, more par-ticularly, a cover-equipped camera provided with a lock sys-tem for locking a cover which is arranged to move between righ-t and left at -the front of a camera body.
Cameras are usually provided with a pro-tection case covering the whole of the camera to protect their lens and fin-der and make them dust-free. However, compact cameras not having a protection case have become popular these days. These compact cameras, however, need something like the protection 10 case to protect and make their lens and finder dust-free when they are carried. There has been thus developed a camera having a cover on the camera body to cover its lens and finder and movable from right and left at the front of said camera body.
The cover-equipped camera of this type, however, has such a dis-advantage that i-t must be ascertained if -the cover is comple-tely opened not shielding i-ts lens and finder at photo--taking time. Namely, -the cover-equipped camera of this type has no means for locking the opened cover, though the cover can be opened to expose the lens and finder. It happens -therefore 20 that the cover is carelessly pushed by the fingers to partially shield the lens and finder~ thus spoiling photos taken. This reduces the capacity of the camera having compactness and easy-handling to achieve quick shuttering ability and other func-tions to maximum exten-t.
According to the present invention therefore there ls provided a cover-equipped camera comprising: a camera body including a finder and a pho-tographic lens; a cover comprising a fixed cover fixed to the camera body and movable cover which is adapted to move laterally between a closed position where the fincler and phol;ographic lens are covered by the fixed and movable covers and an opened position where the finder and the photographic lens are exposed between the fixed and movable ..

covers; a slider ex-tending from the camera body; a sliding guide member provided on -the movable cover and engaged wi-th the slide -to allow the la-teral sliding movement of the movable cover; means for biassing the movable cover toward the opened posi-tion;
an engaging mechanism adapted -to hold the movable cover in the closed position and comprising an engaging projection provided on the movable cover, and a lock lever on the side of the fixed cover and adapted to engage with the engaging projection when the movable cover is in the closed position, said lock lever being biassed vertically in either an upper or lower direc-tion;
an operating lever adapted to release the engagement between the engaging projection and the lock lever when vertically moved against the biassing force; and a stopping means for stopping the movable cover in the opened position. Suitably, the stopping means comprises an iron piece on the sliding guide member and a magnet on the.camera body, or vice versa. Pre-ferably the sliding guide member is o~ C-shape form, the arm portions of which extend laterally outside the lens, and the slider comprises a roller adapted to be fitted into the arms of the sliding guide member. More preferably, the engaging projection comprises two projections which run outside of the lens when -the movable cover is being opened or closed, and the lock lever is in a C-shaped form, the ends oE -the arms of which each have engaging portions for engagement with -the engaging projections, the ver-tical bridge portion o~ -the C-shaped lock lever being slidably engaged with projections on the camera body. Su.itably, -the means Eor biassing the movable cover is a spring attached to the sliding guide member, and the lock lever is biassed by a spring attached between the lever and the camera body.

355i In one embodiment of the present invention the sliding guide member, the slider and the stopping means are positioned inside of a front shielding wall of the camera body, and the lock lever and -the engaging projections are positioned ou-tside of the front shielding wall.
The present invention eliminates the above drawbacks and provides a cover-equipped camera having a cover au-tomati-cally opened when a lever is ligh-tly pushed by the finger tips, and a locking means for locking the opened cover so as not to 10 unintentionally shield the lens and finder.

An embodiment of the present inven-tion will be des-cribed referring to the accompanying drawings. Fig. 1 is a fron-t view of a cover-equipped camera, in which numeral 1 re-presents a camera body, 2 a lens and 3 a finder. Numeral 4 denotes a cover arranged -to move righ-t and lef-t at the front of the camera and contact closely with a Eixed cover 4a -to shield the lens 2 and the finder 3, when closed, so as to achieve pro-tection and dust-free effects, said movable cover 4 being opposite to the fixed cover 4a with the lens 2 interposed -there-between when opened.

, . .. ~_ _.. . .

3~5i The cover 4 has a sliding guide member 5 movable inside and parallel to a front shielding wall la of said camera body 1 and fixed to the cover 4 hy means of screws 5a and 5a.
The sliding guide member 5 is a C-shaped plate and has a sli-t 5b in each of the arms extending parallel -to each other. A
slider comprising a projection 6 extending from the front shielding wall la of said camera body 1 and a collar 7 fitted around the projection 6 is engaged with each of the slits 5b and further includes a stopping member 8 attached to the end 10 of said projection 6 so as to prevent it from coming out o~ the slit 5b. An engaging portion 5c is formed on the upper arm of said sliding guide member 5 and one end of a coil spring 9 is attached to the engaging portion 5c while the o-ther end thereof to an engaging proiection lb extending from the front shielding wall la. The coil spring 9 urges the sliding guide member 5 toward one side of said camera body 1 to normally maintain the cover 4 open and thus -the lens 2 and the finder 3 exposed.
A projection 5d is formed near the engaging portion 5c by bend-ing a part of said sliding guide member 5, and an iron piece 20 10 is attached to the projection 5d. Opposite to this iron piece 10, a permanent magnet 10a is fixed to the inner face of said front shielding wall la. The permanent magnet 10a attracts -the iron piece 10 -to hold the sliding guide member 5 stopped when the sliding guide member 5 moves the cover 4 to opened position as shown in Fig. 1. The permanent magnet 10a may be attached to the s:liding guide member 5.
On the side of the ~ixed cover 4a opposite to the movable cover ~ with the lens interposed between them, are projections 6a and 6a from the outer face of said front shield-30 ing wall la, each of sa:icl projections 6a and 6a having a collarsimilar l:o that oi. said projection 6. ~ lock lever 11 having a slit lla engageable with the projections 6a and 6a is ver-tically 355i movable between the fixed cover 4a and the front shielding wall la. The loclc lever 11 is a C-shaped pla-te and has an engaging por-tion llb at the front end of each of its parallel arms, another engagin~ portion llc extending upwardly from its upper end, and an operating lever lld at its lower end. One end of a coil spring 12 is at-tached to the engaging portion llc while the other endthereof to a pin extends from the outer face of said front shielding wall la, to -thereby urge the lock lever ll normally upwards. The operating lever lld extends outside the 10 fixed cover 4a and is vertically freely movable. The engaging portions llb and llb are engaged wi-th and released from engaging projections 4b and 4b on the inner face of said cover 4 to form latches. Each of -the engaglng projections 4b and 4b as well as each of the engaglng portions llb and llb has striking sloped portions, so that the operatin~ lever ll can be lowered allow-ing the engaging projections 4b and 4b -to be easily engaged with the engaging por-tions llb and llb.
; When the cover-equipped camera according to the pre-sent inven-tion is used, therefore, the opera-ting lever lld is 20 pushed downwards, moving the lock lever ll downward via the slit lla and the projections 6a,6a, the engaging portions llb and llb are engaged with the engaging projections 4b and 4b, namely, -the cover 4 is closely contac-ted with the fixed cover 4a shielding the lens 2 and -the finder 3. When the lock lever ll is moved downwards, the engaging portions llb and llb are released from the engaging projections 4b ancl 4b, respectively.
The sliding guide member 5 in-tegral with -the cover 4 is thus urged by the ac-tion of said coil spring 9 to instantly part ~rom the fixed cover 4a. The sliding guide member 5 can move 30 smoothly through the projections 6,6,6 and -the slits 5b,5b, and the coil spring 9 must have a sufficient force to pull the slid-ing guide member 5 and cover 4. When -the cover 4 is pulled and .~ -then s-topped, the iron piece 10 of said slidi.ng guide member . 5 contac-ts the permanent magnet lOa on the front shielding wall ;¦ la of said camerabody 1 so tha-t -the cover 4 can be locked ex-posing -the lens 2 and the finder 3 ready for photo-taking.
The cover 4 can be thus locked in a posi-tion, as shown in Fig.
1, not shielding the lens 2 and the finder 3 and be unmovable even by light push due to finger tips. When it is -to be closed, the cover 4 is moved toward the fixed cover 4a agains-t the force of said coil spring 9 and permanent magnet lOa. When the cover 10 4 is closely contacted with the fixed cover 4a, the engaging projections 4b and 4b on the inner face of said cover 4 push the engaging portions llb and llb of said lock lever 11 -to slightly move the latter downwards, so tha-t the engaging pro-jections 4b and 4b can-ride over the engaging por-tions llb and llb to make latch engagement wi-th each o-ther. Since the lock lever 11 is usually urged upwards by the action of said coil spring 12, the cover 4 can shield -the lens 2 and finder 3 and keep the camera unready for photo-taking, unless the operating lever lld is pushed downards to release latch engagement. When 20 the operating lever lld is pushed clownwards against the force of said coil spring 12, therefore the cover 4 is instantly opened as already described above.
Thus, the present invention provided a cover-equipped camera having a sliding guide member for guiding the cover and a slider arranged on the camera body and engaged with the slid-ing guide member. Therefore, the cover can move smoothly andlightly. In addition, the cover is normally urged to the open condition, thus prevent:ing the cove.r from becoming a hinderance at photo-taking ti.me. The cover-equipped camera according to 30 the present invention ~urther has a lock lever provided with engaging portions for keeping the cover closed. Therefore, opening and closlng of said cover can be achieved with mechanical 35~
quickness by pushing the opera-ting lever. The cover-equipped camera according to the present invention still further has iron pieces and permanent magnet, so that -the cover can be locked open due to magnetic attraction between the iron piece and -the permanent magnet, thus eliminating any risk that the cover will become a hindexance at photo-taking time. Further, the cover-equipped camera according to the presen-t invention enables its lens and hood to be protec-ted and made dust-free, and has excellent quick shuttering capacit~ at photo-taking 10 time. Including the case where quick shu-ttering is intended, the cover-equipped camera according to the present invention makes it unnecessary to find out whether the cover is opened or not, and also elimina-tes any risk that the cover might be care-lessly moved leaving.uselss photos.
